Why won't rufus mark as unusable detected bad blocks
Because it's not its purpose. The bad blocks check is there to tell you if your drive is defective and nothing else. That's why it is set to stop early if it detects too many bad blocks.
Also, the bad blocks detection is not performed with a specific file system but for the actual low level device, where there is absolutely no way to indicate which blocks are bad.
To accomplish what you want, Rufus would have to keep a list of bad blocks somewhere, and then figure out a way to map the disk blocks to the actual file system blocks, which is next to impossible on modern hardware, since it regularly remaps blocks internally, which means that by the time you have figured out that low level disk block 1234
should map to file system cluster 578
, the internal controller of the device may have remapped the bad block somewhere else.
In short: It is not that simple (or even that possible at all) to accomplish, and that is not the goal of Rufus anyway. Instead our advice is that, if you have a device with bad blocks, you should stop using it, and, because it values your data, Rufus will never help you try to use a device where bad blocks have been detected.

It would seem tools like these don't detect usb flash key bad blocks at low level like rufus, seen as high level clusters/sectors,

because I notice rufus specifies which type of nand test strategy ?

Again, I am not going to help you use a defective drive. Either you use the Rufus bad blocks test, find that it reports no error, and happily continue to use a drive that should be in fully working condition, or Rufus reports errors, in which case you are 100% on your own if you want to continue to use that drive.
Therefore, it makes no sense for Rufus to attempt do more on the bad blocks check than what it already does.

you seem to not understand or not want to understand my question whether rufus detects errors other programs won't ?
from rufus.
I have no idea how other programs perform the bad blocks check, and I have no interest in investigating. As such I can't tell you whether Rufus does XYZ whereas other programs do ABC. All I can tell is that Rufus tests at the block level for each individual block of the disk, which is what you want in a bad blocks detection application, which is all the Rufus bad blocks check is.
If that still doesn't satisfy you, then please invest your own time to investigate differences between applications, because it's not my job to tell you about what other applications do.
